Laser diffraction – Sympatec Helos BF

For the particle size analysis we have, inter alia, the laser diffraction using a Sympatec Helos BF (0.1 up to 875 µm) available. The laser diffraction measuring system consists of a RODOS dispersing unit, coupled with a Helos BF spectrometer.

The RODOS is a universal dry dispersing unit applicable for nearly all kinds of dry powders with particle sizes in the range of < 0.1µm up to approx. 875 µm. The combination of feeding and dispersing enables a smooth, complete and product adaptable dispersion.

Principle of operation

The particles rest in the vibratory feeder VIBRI. Now the chute moves fast up and forward and accelerates the particles. The chute moves fast back downwards. At the reversal point of the chute movement the particles leave the chute. The determination of the particle size results from the degree of diffraction of the laser light.
